Error compiling with python 3.7

[amrit-poudel]

I think this library is quite useful, but I keep getting the following error when I try to use the library along with python 3.7. I am on macosx mojave. python 3.7 was built with brew install python and works perfectly fine. I have built numpy/scipy from source are in the pythonpath. Python side of the library works perfectly fine.

I will appreciate any help. Thanks!

I was able to resolve those errors I reported in my earlier post. The solution is as follows: (I) PyString_FromString must be changed to ---> PyUnicode_FromString (II) Change char name[] = "plotting". ---> wchar_t name[] = L"plotting";

However, I am now encountering another error, which I simply cannot resolve! Help.

I do have glog installed (build from source, and ld_library_path is set to glog/lib).
